PiColorLock Gold Colorimetric Assay Kit Summary

Description
PiColorLock phosphate detection reagent changes colour in the presence of inorganic phosphate (Pi). This can be exploited to measure any enzyme that generates Pi including ATPases, GTPases, phosphatases, heat-shock proteins and DNA unwinding proteins.

The unique formulation of PiColorLock affords enhanced assay linearity, dynamic range and colour stability; it is also possible with PiColorLock to work with unstable substrates (e.g. ATP, GTP) that give high non-enzymatic background signals with other acidic dye-based detection reagents.

FeaturesBenefits
Colorimetric assaySimple, scalable and non-radioactive
Compatible with almost any assay bufferFlexibility over a wide range of existing assays

FAQs for PiColorLock Gold Kit (303-0125). (Showing 1 - 4 of 4 FAQs).

  1. I have phosphate in my enzyme. What can I do?
    • You can dialyse or desalt the enzyme into a phosphate-free buffer. Alternatively, you can use a special resin (PiBind) to remove the phosphate.
  2. I have 5% DMSO in my assay. Can I use PiColorLock Gold?
    • Yes, the reagent is designed for drug screening work and other situations that require DMSO.
  3. I have a high background in my ATPase assay and I definitely do not have free phosphate in my sample
    • This is almost always due to inadequate mixing of the special stabilizer with the sample and detection reagent. Make sure the stabilizer is pipetted up and down several times to ensure thorough mixing.
  4. I would like to measure the conversion of pyrophosphate to phosphate. Can I use the PiColorLock Gold Phosphate Detection System for this purpose?
    • Yes, only the phosphate will give a signal; pyrophosphate will not.
